"The SPACE™ II subwoofer is the ultimate in extreme bass reproduction"Designed without compromise the SPACE™ II is an evolution of the awesome and extremely popular SPACE woofer which sees it keep the same bass making properties but in a new fantastic looking package. Extreme bass, cutting edge design, superior style and severe power, the SPACE II SPL takes subwoofer parameters and specifications to another level. Incorporating the very latest in cutting edge technology, Mechanical Thermal Unity, developed to enhance subwoofer cooling, the subs operate at much higher temperatures with less distortion and stress. Heat is dissipated directly through the front of the lightweight alloy super rigid cone which is seamlessly attached to flanged dual high temperature alloy voice coils and set in dual layer foam surrounds, which means massive power and serious cone excursion. Admiration guaranteed.Mechanical Thermal Unity This latest cutting edge technology has been developed to enhance subwoofer cooling, allowing them to operate at much higher temperatures with less distortion and stress. By using a 1piece alloy cone we have developed a flanged alloy voice-coil that seamlessly fits with absolute UNITY to the bottom of the cone. The combination of alloy cone and alloy voice-coil joined as one allows enhanced cooling to the coil - the coils constant heat generation is now dissipated directly through the alloy cone, which in effect becomes a THERMAL exchanger, as the heat transfers to the cone. The constant MECHANICAL movement of the cone keeps it cool. The process is totally automated and self sufficient - ultimately it allows the subwoofer to sustain operation at much higher temperatures whilst reducing wear and distortion substantially.
